In patients with critical lower extremity ischemia and occlusion of the distal tibial and pedal arteries bypasses to pedal artery branches may offer the only alternative to primary amputation. The results of 22 pedal branch arterial bypasses are reported, and a review of the literature is offered. The charts of 22 patients undergoing pedal branch arterial bypass during a 12-year period were retrospectively reviewed. The results of six additional reports of this technique were also evaluated. In the present series the cumulative primary graft patency rate was 72 per cent after 2 years. The cumulative limb salvage rate during this interval was 82 per cent. Similar graft patency and limb salvage rates were obtained with the approximately 200 other bypasses of this nature as reported in six other series. Pedal branch arterial bypass offers limb salvage results that are comparable to perimalleolar and pedal artery bypasses. In patients with critical limb ischemia and occlusion of distal tibial and pedal arteries, pedal artery branches should be sought as potential outflow sites. Bypasses to these arteries result in good long-term limb salvage, improved survival, and good functional ability for amputation. Pedal artery branch bypasses are a superior alternative to primary amputation.
